[Problem fixed] Hello,
I used to have this same problem with the flickering mouse cursor on the main display. The solution which Quoc Khanh Le (qkle) mentioned in this comment: https://bugs.launchpad.net/ubuntu/+source/xorg- server/+bug/1724307/comments/24 worked for me! I use a laptop Dell Inspiron 7559 with Ubuntu 18.04. My kernel is 4.15.0-55-generic. Using DisplayLink (Dell Docking Station D3100) I have connected 2 external monitors. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724307 Title: [Dell XPS 13 9360] Mouse cursor flickers with one external monitor connected via HDMI+Wavlink WL-UG39DK1V To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1724307/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
